Description

Technical Field

[0001] This utility model belongs to the field of desulfurized gypsum treatment technology, and in particular relates to a flash dryer for desulfurized gypsum treatment. Background Technology

[0002] The treatment of desulfurized gypsum is closely linked to flash dryers. As a highly efficient drying device, flash dryers play a crucial role in the treatment of desulfurized gypsum. Desulfurized gypsum, a byproduct of industrial production, is of great significance for environmental protection and resource recycling through its effective treatment and utilization. Flash dryers, with their unique fluidized bed drying and cyclone drying technologies, can rapidly remove moisture from desulfurized gypsum, achieving ideal drying results. The crushed desulfurized gypsum raw material comes into full contact with warm air inside the flash dryer, completing the drying process in an extremely short time, typically within seconds, resulting in desulfurized gypsum products with extremely low moisture content. This highly efficient drying method not only improves the treatment efficiency of desulfurized gypsum but also facilitates its subsequent utilization, such as as a building material and soil conditioner, realizing the resource utilization of desulfurized gypsum.

[0003] The problem with the existing technology is that when the existing flash dryer is working, some of the gypsum material will solidify into lumps, which will easily accumulate in the hopper during processing and conveying, causing hopper blockage and thus affecting the processing efficiency to a certain extent. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a flash dryer for desulfurized gypsum treatment, which has the advantage of breaking up lumps of gypsum material, avoiding blockage caused by accumulation in the hopper. It solves the problem that in existing flash dryers, some gypsum material will clump together during operation, causing blockage in the hopper during processing and conveying, which will affect the processing efficiency to a certain extent.

[0005] This utility model is implemented as follows: a flash dryer for desulfurized gypsum treatment includes a machine body, a conveying device, a frame, and a hopper. The conveying device is located on the left side of the machine body and is fixedly connected to the machine body. The frame is located below the conveying device and is fixedly connected to the conveying device. The hopper is fixedly connected above the conveying device and communicates with the conveying device. A crushing device is provided inside the hopper, and impact components are provided on both the left and right sides of the hopper.

[0006] The preferred crushing device of this utility model includes a crushing component and a transmission component. There are two crushing components, which are respectively arranged on the left and right sides inside the hopper. The transmission component is arranged in front of the hopper. By setting the crushing device, some lumps of gypsum material are broken up, so as to prevent the lumps of gypsum material from accumulating in the hopper and clogging the hopper, thus affecting the processing and conveying function.

[0007] The preferred crushing assembly of this utility model includes a rotating shaft, a drum, crushing heads, and extrusion wheels. The rotating shaft is disposed inside the hopper, with both its front and rear ends extending out of the hopper and rotatably connected to it. The drum is sleeved on the surface of the rotating shaft and fixedly connected to it. There are several crushing heads, each fixedly connected to the circumference of the drum. There are two extrusion wheels, each sleeved on the front and rear ends of the rotating shaft and fixedly connected to it. By setting up the crushing assembly, it is used to rotate and break up lumps of gypsum material, which can prevent clogging and facilitate subsequent flash evaporation and fixation.

[0008] The preferred transmission assembly of this utility model includes a first pulley, a motor, and a second pulley. There are two first pulleys, which are respectively fixedly connected to the front ends of the two rotating shafts. The two second pulleys are connected by a belt. The motor is located on the right side of the hopper and is fixedly connected to the upper surface of the frame. The second pulley is fixedly connected to the output end of the motor. The second pulley is connected to the first pulley on the right side via a belt. By setting up the transmission assembly, it is used to drive and control the two crushing components and the two impact components.

[0009] The preferred tapping assembly of this utility model includes a rotating seat, a tapping plate, tension springs, and linkage components. The rotating seat is fixedly connected to the upper right side of the hopper. The upper end of the tapping plate is sleeved on the surface of the rotating seat and rotatably connected to the rotating seat. There are three tension springs, all located on the left side of the tapping plate. The left and right ends of the three tension springs are fixedly connected to the left surface of the tapping plate and the right surface of the hopper, respectively. There are two linkage components, located on the front and rear sides of the tapping plate, respectively. By setting up the tapping assembly, the hopper is tapped to generate vibration, thereby improving the flowability of the gypsum material in the hopper, making the gypsum material fall more smoothly, and thus preventing blockage.

[0010] The preferred linkage component of this utility model includes a connecting rod and an extrusion plate. The connecting rod is fixedly connected to the front surface of the clapping plate, and the extrusion plate is fixedly connected to the left end of the connecting rod. By setting the linkage component, it is used to link with the two crushing components. By cooperating with the extrusion wheel, it links with the clapping component to perform a clapping action when the crushing component rotates and crushes, while saving the cost of adding a drive source.

[0011] As a preferred embodiment of this invention, rubber blocks are fixedly connected to the surfaces of the two clappers that are close to each other. The sides of the two rubber blocks that are close to each other are in contact with the left and right sides of the hopper, respectively. By setting rubber blocks on the surfaces of the two clappers that are close to each other, the hopper is directly slapped, which can prevent damage to the hopper when the clappers are slapped.

[0012] 1.

[0018] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown in the figure, a flash dryer for desulfurized gypsum treatment provided by this utility model embodiment includes a machine body 1, a conveying device 2, a frame 3, and a hopper 4. The conveying device 2 is located on the left side of the machine body 1 and is fixedly connected to the machine body 1. The frame 3 is located below the conveying device 2 and is fixedly connected to the conveying device 2. The hopper 4 is fixedly connected above the conveying device 2 and communicates with the conveying device 2. A crushing device 5 is provided inside the hopper 4, and a striking component 6 is provided on both the left and right sides of the hopper 4.

[0021] refer to Figure 1 and Figure 2 The crushing device 5 includes a crushing component 51 and a transmission component 52. There are two crushing components 51, which are respectively arranged on the left and right sides inside the hopper 4. The transmission component 52 is arranged in front of the hopper 4.

[0022] The above solution involves setting up a crushing device 5 to break up lumps of gypsum material, preventing them from accumulating in the hopper 4 and clogging the hopper 4, thus affecting the processing and conveying function.

[0023] refer to Figure 2 and Figure 3 The crushing assembly 51 includes a rotating shaft 511, a drum 512, a crushing head 513, and an extrusion wheel 514. The rotating shaft 511 is located inside the hopper 4 and extends out of the hopper 4 at both ends and is rotatably connected to the hopper 4. The drum 512 is sleeved on the surface of the rotating shaft 511 and is fixedly connected to the rotating shaft 511. There are several crushing heads 513, all of which are fixedly connected to the circumference of the drum 512. There are two extrusion wheels 514, which are respectively sleeved on the front and rear ends of the rotating shaft 511 and are fixedly connected to the rotating shaft 511.

[0024] The above solution involves setting up a crushing component 51 to rotate and break up the lumps of gypsum material, which helps to prevent blockages and facilitates subsequent flash evaporation and fixation.

[0025] refer to Figure 1 and Figure 2The transmission assembly 52 includes a first pulley 521, a motor 522, and a second pulley 523. There are two first pulleys 521, which are fixedly connected to the front ends of two rotating shafts 511 respectively. The two second pulleys 523 are connected by a belt. The motor 522 is located on the right side of the hopper 4 and is fixedly connected to the upper surface of the frame 3. The second pulley 523 is fixedly connected to the output end of the motor 522. The second pulley 523 is connected to the first drive pulley 521 on the right side by a belt.

[0026] The above scheme is adopted: by setting up a transmission component 52, it is used to drive and control the two crushing components 51 and the two impact components 6.

[0027] refer to Figure 2 , Figure 3 and Figure 4 The striking assembly 6 includes a rotating seat 61, a striking plate 62, a tension spring 63, and a linkage 64. The rotating seat 61 is fixedly connected to the upper right side of the hopper 4. The upper end of the striking plate 62 is sleeved on the surface of the rotating seat 61 and rotatably connected to the rotating seat 61. There are three tension springs 63, all of which are located on the left side of the striking plate 62. The left and right ends of the three tension springs 63 are fixedly connected to the left surface of the striking plate 62 and the right surface of the hopper 4, respectively. There are two linkages 64, which are located on the front and rear sides of the striking plate 62, respectively.

[0028] The above solution is adopted: by setting up the tapping component 6, it is used to tap the hopper 4, which taps the hopper 4 to make it vibrate, thereby improving the flow of gypsum material in the hopper 4, making the gypsum material fall more smoothly, and thus preventing blockage.

[0029] refer to Figure 2 , Figure 3 and Figure 4 The linkage 64 includes a connecting rod 641 and a pressing plate 642. The connecting rod 641 is fixedly connected to the front surface of the clapping plate 62, and the pressing plate 642 is fixedly connected to the left end of the connecting rod 641.

[0030] The above solution is adopted: by setting up a linkage component 64, which is used to link with the two crushing components 51, and by cooperating with the extrusion wheel 514, it links with the striking component 6 to perform a striking effect when the crushing component 51 rotates and crushes, while saving the cost of adding a drive source.

[0031] refer to Figure 2 and Figure 4 Rubber blocks 7 are fixedly connected to the surfaces of the two clappers 62 that are close to each other, and the sides of the two rubber blocks 7 that are close to each other are in contact with the left and right sides of the hopper 4, respectively.

[0032] The above solution involves placing rubber blocks 7 on the surfaces of the two clappers 62 that are close to each other, which serves to directly strike the hopper 4 and prevent damage to the hopper 4 when the clappers 62 strike it.

[0033] In operation, the control motor 522 starts, driving pulley 521 to rotate. The rotation of pulley 521 drives pulley 523 via a belt, and the two pulleys 523 rotate via the belt. The rotation of pulleys 523 drives the rotating shaft 511 to rotate, which in turn drives the drum 512 to rotate. Simultaneously, the drum 512 drives several crushing heads 513 to rotate. At this time, gypsum material is poured into the hopper 4. The lumps of gypsum material are broken up by the impact of the rotating crushing heads 513. The rotation of the rotating shaft 511 also drives the extrusion rollers 514 at both ends to rotate. 14. Rotating the protrusion of the extrusion wheel 514 applies pressure to the extrusion plate 642. The extrusion plate 642 is compressed, which pushes the connecting rod 641 to move. The moving connecting rod 641 pushes the clapper 62 to rotate on the surface of the rotating seat 61. While the clapper 62 is rotating, it stretches the tension spring 63 and moves the rubber block 7 away from the hopper 4. When the extrusion wheel 514 rotates to the point where the protrusion no longer compresses the extrusion plate 642, the tension spring 63 will rebound, quickly rotating and pulling the clapper 62 back. At the same time, the clapper 62 drives the rubber block 7 to strike the hopper 4. Through the repeated compression and release of the extrusion plate 642 by the extrusion wheel 514, the clapper 62 is driven to reciprocate to strike the hopper 4, preventing it from getting blocked.

[0034] In summary, this flash dryer for desulfurized gypsum treatment, through the coordinated use of a machine body 1, conveying device 2, frame 3, hopper 4, crushing device 5, crushing component 51, rotating shaft 5111, drum 512, crushing head 513, extrusion wheel 514, transmission component 52, pulley one 521, motor 522, pulley two 523, striking component 6, rotating seat 61, striking plate 62, tension spring 63, linkage component 64, connecting rod 641, extrusion plate 642, and rubber block 7, solves the problem that in existing flash dryers, some gypsum material agglomerates into lumps, easily accumulating in the hopper during processing and conveying, causing hopper blockage and thus affecting processing efficiency to a certain extent.
